| Genera | |
Tritheledontidae, the tritheledontids or ictidosaurs,eutriconodonts. They are known from finds in South America and South Africa, indicating that they may have lived only on the supercontinent of Gondwana. The family Tritheledontidae was named by South African paleontologist Robert Broom in 1912.[2] The family is often misspelled "Trithelodontidae".
It is possible that tritheledontids had vibrissae, according to the PBS documentary, Your Inner Fish.[3] A common ancestor of all therian mammals did so.[4] It is possible that the development of the whisker sensory system played an important role in mammalian development, more generally.[4]
